ABSTRACT:
A motion picture camera has a film receiving chamber with an image recording location and a sound recording location. When a sound film is loaded, it is guided to through both locations whereas when a silent film is loaded, it is guided through only the image recording location. A first film feed device and a second film feed device are provided; the first of which transports the film at the image recording location intermittently and the second film feed device transports the film at the sound recording location at a substantially constant speed. Apparatus are provided to detect disorder or abnormal change in operations of the camera and to stop the motion of the camera when such change occurs.
